The German Protestant Home for Orphans and Old People was located in Ward 14 of Detroit, Michigan in 1920, Enumeration District 433.
Because of the Ethnic Spelling of several of these Employees and Residents, there are probably several errors. I'm not even gonna pretend I could tell what the letters were, many I couldn't make out, the hand writing is difficult to translate, and I am not particuliarly familiar with German spellings. Some of the residents and employees had towns/cities of birth, however those too were very difficult to make out the appropriate spelling.
This is an index only, for full details and to double check the surname spellings, view the 1920 Detroit, Ward 14 Census.

Below are the Employees and Residents of the Orphan and Old People's Home in 1920. All the Orphans are under age 14 yrs, and therefore Single.
